[0010] Furthermore, a mounting groove is provided below the guide rail, a cleaning brush is installed inside the mounting groove, and a support rod is fixedly connected to one side of the top of the lower frame.

[0011] By adopting the above technical solution, by opening an installation groove under the guide rail and installing a cleaning brush inside the groove, the automatic cleaning function of the guide rail is achieved. During the sliding process of the door and window, the cleaning brush can effectively remove dust and debris to keep it clean.

[0012] Furthermore, a lower supporting wheel is rotatably connected inside the lower mounting frame, and the lower supporting wheel abuts against the supporting rod.

[0013] By adopting the above technical solution, the lower support wheel rotatably connected inside the lower mounting frame abuts against the support rod, providing bottom support and sliding functions for the doors and windows, which can disperse the weight of the doors and windows, reduce the wear on a single component, and thus extend the service life of the doors and windows.

[0014] Furthermore, a plurality of guide wheels are provided, and the plurality of guide wheels are linearly and evenly arranged.

[0015] By adopting the above technical solution, by setting up multiple guide wheels and arranging them linearly and evenly, the contact points between doors and windows and guide rails are increased, thereby improving the stability and smoothness of sliding. Multiple guide wheels share the weight of doors and windows and the friction during sliding, effectively reducing single-point wear and extending the service life of guide wheels and guide rails.

[0016] Furthermore, a plurality of the lower support wheels are provided, and the plurality of the lower support wheels are linearly and evenly arranged.

[0017] By adopting the above technical solution, by setting up multiple lower support wheels and arranging them linearly and evenly, the supporting stability and load-bearing capacity of the bottom of doors and windows are enhanced. Multiple lower support wheels share the weight of doors and windows, reducing the load of a single wheel, thereby extending the service life of the lower support wheels.

[0018] In summary, the utility model mainly has the following beneficial effects:

[0019] 1. The utility model sets a guide wheel and a lower support wheel. Since it adopts an upper and lower double-row wheel design, that is, an upper guide wheel and a lower support wheel, this sliding door and window structure is more stable than the traditional single-row wheel design and is not easy to derail. Multiple guide wheels and lower support wheels are evenly arranged linearly, so that the door's load-bearing capacity is more uniform, further enhancing stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0027] The following describes an embodiment of the utility model based on its overall structure.

[0028] A double-row wheeled sliding door and window structure, such as Figure 1-Figure 5 As shown, it includes an upper frame 1 and a lower frame 2, a sliding door mechanism 3 is provided between the upper frame 1 and the lower frame 2, and guide rails 4 are fixedly connected to both sides of the inner wall of the upper frame 1;

[0029] The sliding door mechanism 3 includes an upper mounting frame 301, and guide wheels 302 are rotatably connected to both sides of the upper mounting frame 301, and the guide wheels 302 are abutted against the guide rails 4. Through this upper and lower double-row wheel sliding door and window structure, the sliding stability and smoothness of the doors and windows are significantly improved. Since the guide wheels 302 are rotatably connected to both sides of the upper mounting frame 301, and the guide wheels 302 are abutted against the guide rails 4 fixedly connected to both sides of the inner wall of the upper frame 1, such a design enables the doors and windows to slide smoothly along the guide rails 4 during the pushing and pulling process, effectively avoiding the occurrence of derailment. At the same time, due to the cooperation between the guide wheels 302 and the guide rails 4, the friction resistance of the doors and windows during the sliding process is reduced, thereby reducing wear and extending the service life of the doors and windows.

[0030] See also Figure 1 , Figure 2 and Figure 4The upper mounting frame 301 is fixedly connected to the inside of the door panel 303, and the bottom of the door panel 303 is fixedly connected to the lower mounting frame 304. By fixing the door panel 303 to the inside of the upper mounting frame 301, the stability and safety of the door panel are ensured, and the door panel is effectively prevented from shaking or falling off during the pushing and pulling process, thereby improving the overall structural strength and stability of the doors and windows. At the same time, the lower mounting frame 304 fixedly connected to the bottom of the door panel 303 further enhances the load-bearing capacity and stability of the doors and windows. The lower mounting frame 304 can not only share the weight of the door panel, but also serve as a supporting structure at the bottom of the doors and windows to prevent the doors and windows from tilting or deforming during the pushing and pulling process, thereby ensuring the normal use and life of the doors and windows.

[0031] See also Figure 1 , Figure 2 and Figure 5 A mounting groove 5 is provided below the guide rail 4, and a cleaning brush 6 is installed inside the mounting groove 5. A support rod 7 is fixedly connected to one side of the top of the lower frame 2. By providing a mounting groove 5 below the guide rail 4 and installing a cleaning brush 6 therein, the automatic cleaning function of the guide rail 4 is realized. During the sliding process of the doors and windows, the cleaning brush 6 can effectively remove dust and debris to keep them clean. At the same time, the support rod 7 fixedly connected to one side of the top of the lower frame 2 provides an additional support point for the doors and windows, further enhancing the stability and load-bearing capacity of the doors and windows. The support rod 7 can share the weight of the doors and windows, and play a guiding and positioning role during the sliding process of the doors and windows, effectively preventing the doors and windows from offsetting or shaking during the pushing and pulling process, thereby improving the safety and service life of the doors and windows.

[0032] See also Figure 1 , Figure 2 and Figure 5 The lower supporting wheel 305 is rotatably connected inside the lower mounting frame 304, and the lower supporting wheel 305 abuts against the supporting rod 7. The lower supporting wheel 305 rotatably connected inside the lower mounting frame 304 abuts against the supporting rod 7, providing bottom support and sliding functions for the doors and windows, which can disperse the weight of the doors and windows and reduce the wear on a single component, thereby extending the service life of the doors and windows. At the same time, the rotating connection of the lower supporting wheel 305 makes the doors and windows smoother when sliding, reduces friction resistance, and improves the user experience.

[0033] See also Figure 3, a plurality of guide wheels 302 are provided, and the plurality of guide wheels 302 are linearly and evenly arranged. By providing a plurality of guide wheels 302 and arranging them linearly and evenly, the contact points between the doors and windows and the guide rail 4 are increased, thereby improving the stability and smoothness of sliding. The plurality of guide wheels 302 jointly share the weight of the doors and windows and the friction during sliding, effectively reducing single-point wear and extending the service life of the guide wheels and guide rails. At the same time, the plurality of evenly arranged guide wheels 302 can also better adapt to the slight bending or unevenness of the guide rail 4, maintain the levelness and straightness of the doors and windows during the sliding process, avoid the problem of jamming or deviation from the track due to the unevenness of the guide rail, and further improve the user experience.

[0034] See also Figure 3 There are multiple lower support wheels 305, and the multiple lower support wheels 305 are arranged linearly and evenly. By setting multiple lower support wheels 305 and arranging them linearly and evenly, the supporting stability and load-bearing capacity of the bottom of the doors and windows are enhanced. The multiple lower support wheels 305 share the weight of the doors and windows, reducing the load of a single wheel, thereby extending the service life of the lower support wheels. At the same time, the multiple evenly distributed lower support wheels 305 can better cooperate with the support rod 7, reduce friction and resistance during sliding, make the pushing and pulling operations of the doors and windows smoother, and improve the user experience.

[0035] The implementation principle of the utility model is as follows: first, the user can open or close the sliding door by pushing the door panel 303. Since the guide wheels 302 are rotatably connected on both sides of the upper mounting frame 301, these guide wheels 302 slide along the guide rails 4 fixedly connected on both sides of the inner wall of the upper frame 1, so that the opening and closing of the door becomes smooth. At the bottom of the door, the lower support wheel 305 rotatably connected inside the lower mounting frame 304 will slide along the top of the lower frame 2 or the support rod 7, further enhancing the stability and sliding smoothness of the door. An installation groove 5 is provided under the guide rail 4, and a cleaning brush 6 is installed inside. When the door slides, the cleaning brush 6 can automatically clean the bottom of the guide rail 4 to prevent dust from entering, thereby extending the service life and ensuring smooth sliding.
